Title:
FILM AND METHOD FOR PRODUCING SAME, LAMINATED STRUCTURE, LAMINATED GLASS, AND AUTOMOBILE
Document Type and Number:
WIPO Patent Application WO/2024/062961
Kind Code:
A1
Abstract:
The present invention addresses the problem of providing a film that is highly suitable for processes for laminating functional layers involving heating and is capable of suppressing uneven warping resulting from heat press molding for obtaining laminated glass including an intermediate layer and a support body. The present invention provides a film that has at least one thermoplastic resin layer and is characterized in that when the rate of shrinkage at a temperature of TºC in a heat shrinkage curve is represented by S(T)% and a direction in which S(150) is the largest among one discretionary direction and directions reached by rotating by intervals of 5º to 180ºC in an in-plane direction parallel to the film surface from said one discretionary direction in a plane parallel to the film surface is designated as an X direction, 0.50 ≤ | S(150) - S(100)| and 0.00 ≤ |S(120) - S(100)| ≤ 0.40 are satisfied in the X direction.
